Application of Nanotechnology in Cosmetics 沙迪, I201420052 Abstract The Science of controlling particles and atoms in the nanoscale is called Nanotechnology, which is 80,000 times tinier than the width of a human’s hair. The utilization of nanotechnology has extended over different branches of science, from electronics to medicine. However, nanotechnology has now discovered applications in the field of beauty care products which is called Nano-cosmetics. This widespread influence of nanotechnology in the
Nanotechnology What is Nanotechnology? Nanotechnology is the study and utilization of amazingly little things and can be utilized over the various science fields such as chemistry, physics, materials science, biology, and engineering. Nanotechnology includes shrinking down objects so they can perform mechanical, electrical, or chemical processes at a much littler scale. Nanotechnology include the capacity to see and to control singular particles and atoms. Everything on Earth is comprised of particles:
world is getting more complex until the level of technology has increases rapidly years by years. There are smarter and genius people keep doing research to achieve their goals and make the life easier and better. So, in some senses, the term ‘nanotechnology’ is not a new thing in this millennium era as it already existed since 1959. Basically, nano- is one of SI prefix which means a billionth of a meter. To compare a size of nanometer to a meter is like a size of football to a size of the earth.
Executive Summary Nanotechnology is the study of minute things and can be applied in all science fields such as chemistry, biology, materials science, physics and engineering. The concept is to be able manipulate and control individual atoms and molecules. With the technology, nanoscale materials can be of an enhancement in strength, lighter weight and greater chemical reactivity. Nanotechnology products have been widely used in our daily life such as cosmetics, automotive parts, insulators, dental
experiment a tiny entity known as Maxwell’s Demon able to handle individual molecules. In 1959, Cattech physicist Richard Feynman gives his famed talk “There’s Plenty of Room at the Bottom”, outlining the prospects for atomic engineering Nanotechnology can be defined as the study of fabrication, design, characterization and application of structure and systems by controlling the shape and size at a nanometer scale . It is concerned with
Heavy metal contamination has been a serious problem for the past decade. It is considered as one of the most dangerous types of aquatic pollutions because of its toxicity and accumulation by marine organisms (El Zokm, El-Gohary & El-Khalek, 2012). Many heavy metals find their way to bodies of water through a wide range of mechanisms and pathways, including to the air such as during combustion, extraction, and processing and to surface waters via runoff and releases from storage and transport as
flora and inhabit various areas in the body such as the oral cavity, nose, skin, nasopharynx, oropharynx, gastrointestinal tract, genitalia, urethra, vagina as well as the external ear. These organisms most of the time are non pathogenic, but in some cases especially in immunosuppressed patients, they may cause diseases. Bacteria that can cause infection are called pathogenic bacteria. Examples
